CSPP/Cirlotron - Brand Names of Commercial Solid State Amplifiers
About
http://www.diyaudio.com/forums/solid...put-stage.html I have listet some URLs, mostly basic articles and diy projects. From the commercial brands with circlotron topology inside by solid state power output I know only "SUMO" (and several others with tubes like GRAAF GM-20). BAT (Balanced Audio Technology) perhaps uses also this topology by their solid state amps, but this I don't know exactly (schematic information wanted). Which additional commercial brands uses this cross shunt push pull topology in their solid state amplifiers? Thank you very much for your advices in advance. |
really no informations about commercial circlotron solid state models?
The invention of the Circlotron amplifier has generally been generally attributed to Alpha M. Wiggins of Electro-Voice, Inc., Buchanan, Michigan. more basic informations about this topology are there: Circlotron History Page |
Maybe you did not look hard enough :
6moons audio reviews: Thorens TEM 3200 Stereoplay, das Magazin fr Hifi, Surround und Musik - Know-how The output stage, which is circlotron, is SS. The front end is just normal tube gain stage. Patrick |

Are there any news?
|
I have heard, that Yamaha or DENON has introduce amplifiers with this CSPP topology. Who knows more ?

Hi Tiefbass !
Yes Yamaha introduced two SS Amps that use Circlotron topology , AS2000 & As 1000 , here is Yamaha commercial flyer with block schematics . BTW you have forget to mention Atma-Sphere manufacture . Best Regards ! |

Atma-Sphere music systems, inc. unfortunately tube amplifiers. Quote:
Schematics are here for the models "A-S2000" and "A-S1000": http://elektrotanya.com/yamaha_a-s20.../download.html http://elektrotanya.com/yamaha_a-s10.../download.html |
Hi Tiefbass !
After my provisional analyze of Yamaha AS series of Circlotron based SS Amp I have concluded that both Amps circuitry is too much complex , any way to have both original Yamaha manual from your links is not bad for future service purposes . On the other hand Atma-Sphere founder & main circuit designer Mr.Ralph Karsten have fully supported DIY community to DIY his M60 OTL Circlotron tube Amp here : http://www.diyaudio.com/forums/tubes...ube-amp-2.html Best Regards ! |
